Interface AnnotationListener

All Known Implementing Classes:

CommandPanel, ControlPanel, Frame, HistogramData, PitchClassHistogramPanel, PitchContour

public interface AnnotationListener

Elements interested in representing annotations should implement this interface. The implementor should be able to clear all annotations and reset a subset of annotations rather quickly.

Method Summary

void	addAnnotation(Annotation annotation) Add an annotation to the element.
void	annotationsAdded() Is called after a list of annotations is added.
void	clearAnnotations() Clears all annotations.
void	extractionFinished() A hook to react to annotation extraction.
void	extractionStarted() A hook to react to annotation extraction.

Method Detail

addAnnotation

void addAnnotation(Annotation annotation)

Add an annotation to the element.

Parameters:

annotation - The annotation to add: this method is called a lot. After a clearAnnotations() call a very large number of annotations is possible. So efficiently adding annotations should be possible or threaded.

clearAnnotations

void clearAnnotations()

Clears all annotations.

annotationsAdded

void annotationsAdded()

Is called after a list of annotations is added.

extractionStarted

void extractionStarted()

A hook to react to annotation extraction. This method is called when pitch annotations starts on an audio file.

extractionFinished

void extractionFinished()

A hook to react to annotation extraction. This method is called when pitch annotations is completed.
